Preferred Drug List (PDL)

On January 1, 2020, all managed care plans and Apple Health fee-for-service programs will continue to phase in a Single Preferred Drug List (PDL).

This change is mandated by the Washington State Legislature.

The Health Care Authority is working with managed care plans that serve Apple Health clients to create the Apple Health PDL. Managed-care plans will continue to use their own preferred drug lists for drugs not included in the Apple Health PDL.

Please contact [email protected] with any questions.

Personal Medication Coach Program

The Personal Medication Coach Program works with doctors and patients to ensure that medications are effective and being used correctly.

The Personal Medication Coach Program is a service for members with multiple health conditions and who take multiple medications. This program is offered through a partnership between CHPW and MedWiseRx.

If you believe one of your patients would benefit from Personal Medication Coaching, ask them to visit the MedWiseRX website or call 1-844-866-3730 to get started.

Eligibility Requirements

If you are looking for Medication Therapy Management for a Medicare Advantage member, visit the CHPW Medicare Advantage website for information on Medicare Medication Therapy Management information.

Patient Review and Coordination Program

Our Patient Review and Coordination (PRC) Program helps members use their medical services safely and appropriately.

Members who are selected for PRC must choose one primary care provider, pharmacy, and hospital. One primary care provider makes sure medical care and prescriptions are coordinated for the health and safety of the member.

To refer a patient to the PRC program or learn more, call us at 1-866-907-1902.

Second Opinion Program

As mandated by the legislator in RCW 74.09.490, HCA has developed the second opinion program to improve prescribing practices in children.

In collaboration with The Pediatric Mental Health Advisory Group and the Drug Utilization Review Board, HCA has established pediatric mental health guidelines to identify children who may be at high risk due to off-label use of prescription medication, use of multiple medications, high medication dosage, or lack of coordination among multiple prescribing providers.

Helpful resources:

Partnership Access Line (PAL)

To assist prescribers in meeting the needs of children with a mental health diagnosis, and to minimize the need for required SON review, providers can contact the Partnership Access Line (PAL). PAL is a telephone based child mental health consultation system funded by the state legislature, being implemented in Washington State. PAL employs child psychiatrists, child psychologists, and social workers affiliated with Seattle Children’s Hospital to deliver consultation services. The PAL team is available to any primary care provider throughout Washington State.

PCPs may call 1‐866‐599‐7257 between 8am and 5pm for any type of mental health issue that arises with any child, not just CHPW members. For additional information on the PAL visit Seattle Children’s website.
